Jun 25, 2017 · A cilium, or cilia (plural), are small hair-like protuberances on the outside of eukaryotic cells. They are primarily responsible for locomotion, either of the cell itself or of fluids on the cell surface.

A cilium is assembled and built from a basal body on the cell surface. From the basal body, the ciliary rootlet forms ahead of the transition plate and transition zone where the earlier microtubule triplets change to the microtubule doublets of the axoneme.

Cilium, short eyelashlike filament that is numerous on tissue cells of most animals and provides the means for locomotion of protozoans of the phylum Ciliophora. Cilia may be fused in short transverse rows to form membranelles or in tufts to form cirri.

Jun 28, 2016 · Recent studies have begun to clarify the key mechanisms that link cilium assembly and disassembly to the cell cycle, and suggest new possibilities for therapeutic intervention.

Aug 4, 2006 · Almost every vertebrate cell has a specialized cell surface projection called a primary cilium. Although these structures were first described more than a century ago, the full scope of their functions remains poorly understood.

Apr 3, 2009 · Here, we highlight properties of vertebrate cilia, with particular emphasis on their relationship with other subcellular structures, and explore the physiological consequences of ciliary dysfunction. Cilia are polarized structures that appeared early in …

In general, the primary cilium is a sensory organelle that responds to mechanical and chemical stimuli in the environment, communicates that external signal to the cell's interior. However,...

The primary cilium, which was first so named by Sergei Sorokin (Sorokin, 1968), is a solitary organelle that emanates from the cell surface of most mammalian cell types during growth arrest. Increasing evidence suggests that primary cilia are key coordinators of signaling pathways during development and in tissue homeostasis and, when defective ...

Cilia are microtubule-based structures that protrude from the cell surface, and function as sensors for mechanical and chemical environmental cues that regulate cellular differentiation or division.

What decides whether a cell develops a primary cilium or not? What prevents almost every cell type so far examined that has 9 + 2 cilia from also developing primary (9 + 0) cilia?
